Note 4: Voltages on pins other than DV, GND or V
DD may exceed 0.5 volt above or below the supply voltages provided the current is limited to 1 mA.
Note 5: The application of DV voltages higher than required to bring the output to positive full scale may cause device damage.
* NOTICE: Stresses greater than those listed above may cause permanent damage to the device. These are stress ratings only.
Functional operation of the device at or above these conditions is not implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.
